Questions about “safe TB-500” usually turn out to be questions about quality: is the material what the label says, and has it been handled properly? These answers focus on those points for laboratory work.
How do I know the material is what the label says?
Check the certificate of analysis. It should name the compound, the lot number, the methods used (typically HPLC for purity and mass spectrometry for identity) and the test date, and the lot should match your vial. A certificate of analysis is available on request through our contact page, and our products are purity-tested by an independent third-party lab. Our guide to reading a COA explains what each section of the report should contain.
Is TB-500 the same as thymosin beta-4?
No. TB-500 is a synthetic peptide based on the actin-binding region of thymosin beta-4, a naturally occurring 43-amino-acid protein that regulates actin, the main structural protein of the cell cytoskeleton. Make sure the label and the COA describe the same molecule.
How should lyophilized TB-500 be stored and handled?
Keep vials sealed and protected from moisture and light until use. Reconstitute only what the experiment needs, using a solvent suited to your method. bacteriostatic water is a common laboratory choice. Record the lot number, solvent and date.
What formats are available?
TB-500 5mg, TB-500 10mg, TB-500 Capsules and the 1:1 BPC-157 / TB-500 Blend 10mg.
Is TB-500 safe for human use?
TB-500 is not approved by the FDA or any other regulator for any indication, and we make no safety claims for any use. TB-500 and thymosin beta-4 appear on the World Anti-Doping Agency’s prohibited list under S2 (peptide hormones, growth factors, related substances and mimetics). It is sold strictly for laboratory research, and we do not provide dosing, administration or usage guidance.
